A Staten Island elementary school teacher convicted of manslaughter could be returned to the classroom after prosecutors dropped attempted murder charges against her, officials said yesterday.

Despite the collapsed criminal case, Department of Education officials said they’re seeking to boot renegade educator Kim DePrima — who was busted in January after her ex-boyfriend’s home was riddled with bullets.

DePrima’s friend, Sean Hicks, pleaded guilty to the shooting.

Prosecutors said they dropped the case against DePrima after both Hicks and the ex-boyfriend cleared her of any wrongdoing.

The city first tried to eject DePrima, who taught at PS 57, after her two pit bulls mauled a 90-year-old neighbor to death in August 2008 — prompting the manslaughter conviction. But an independent arbitrator ruled DePrima’s negligence at home didn’t affect her role as a special-education teacher.
